Hebrews 4:7
God again designated a certain day as “Today,” when a long time later He spoke through David as was just stated: “Today, if you hear His voice, do not harden your hearts.”
Berean Standard Bible
Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts.
he again defines a certain day, “today”, saying through David so long a time afterward (just as has been said), “Today if you will hear his voice, don’t harden your hearts.”
